Conbraco 12-205-08 Valve

The Conbraco 12-205-08 Valve is a rugged, ASME Section IV certified steam pressure relief valve engineered for 2" NPT configurations. This high-capacity safety valve is factory set at 15 PSI, delivering a substantial steam discharge rate of 2,500 pounds per hour. Ideal for medium to large commercial boilers, it features a heavy-duty cast bronze body and a top-guided design to ensure precise disk alignment and reliable overpressure protection. The internal PTFE-faced elastomer soft seat provides a bubble-tight seal that resists simmering and leakage, minimizing system downtime. Designed with a 2" male NPT inlet and a 2" female NPT outlet, its compact vertical profile includes a 3/8" NPT side tapping for a drain connection to effectively manage condensate. A rust-proof steel spring and stainless steel internals maintain operational integrity in harsh steam environments up to 250°F, making the Apollo 12-205-08 a standard for industrial boiler overpressure protection.

• High Discharge Capacity: Certified to vent 2,500 lbs/hr, sufficient for significant commercial steam loads.
• Positive Soft Sealing: The TFE-coated EPDM seat prevents seat sticking and ensures a tight shut-off after cycling.
• Corrosion Resistance: Full bronze construction and stainless steel spring internals handle saturated steam without premature degradation.
• NBBBI Certified: National Board certified capacity at 15 PSI to satisfy strict local mechanical codes and safety audits.
• Operational Reliability: Top-guided nozzle design ensures the valve resets correctly after every pressure excursion.

Is the set pressure adjustable in the field?
No, this valve is factory set and sealed at 15 PSI to comply with ASME Section IV safety standards; tampering with the setting is not recommended.

What is the purpose of the 3/8" side tapping?
This port is designed for a drain pipe connection, allowing accumulated condensate to be safely diverted away from the valve seat to prevent water hammer or corrosion.

Can this valve be used for liquid or air service?
This specific model is calibrated and certified exclusively for low-pressure steam service; verify local codes before using it for alternative media.
